Short Term Rental on popular river, liability questions

[Nick Frank]

Hello BP community, this is my first post in the forums and wanted to say thanks to any replies in advance! I just bought my first short term rental investment property on a popular river for kayaking and camping in my state. I am currently planning to rent out a tiny cabin on the property this summer. In the fall/winter I plan to build several more small cabins on the property. First, I wanted to see if it would be better to transfer the property into an LLC immediately or if it's ok to wait a year and get umbrella coverage and short term rental coverage for the property for the time being until I build? Secondly, I wanted to make kayaks and rafts available to the guests if possible because I have an access point on my property and want to take advantage of the public drop off points in the area. With the kayaks and rafts being an additional liability, I was wondering if there is anything else I need to do to protect my assets if something were to happen?
